    Description

    FlyBase curator comment: this entry is used to capture phenotypic information when the particular allele (or allele combination) used by the author could not be determined but the context of the experiment suggests that the phenotype being described is some kind of loss of function.

        The ommatidial polarity defects caused by pkunspecified are not modified by one copy of bdgGMREP.

        The ommatidial polarity defects seen in bdgGMREP homozygotes are dominantly suppressed by pkunspecified.
